Methods and apparatuses for transmitting control information

Abstract

Embodiments of the present disclosure relate to methods and devices for transmitting control information. In example embodiments, a method implemented in a network device is provided. According to the method, a first configuration for transmitting first control information from the first network device to a terminal device is determined based on a first control resource set (CORESET). The first configuration being different from a second configuration for transmitting second control information from a second network device to the terminal device and the second configuration being determined based on a second CORESET. The first control information is transmitted to the terminal device based on the first configuration.

What is claimed is: 
     
       1. A method performed by a terminal device, comprising:
 performing a detection for a first control information in a first control resource set (CORESET) and a second control information in a second CORESET, wherein a first set of resource elements (REs) in the first CORESET are allocated for transmitting the first control information via a first control channel and a second set of REs in the first CORESET are allocated for transmitting a first reference signal (RS) associated with the first control channel, and a first set of REs in the second CORESET are allocated for transmitting the second control information via a second control channel and a second set of REs in the second CORESET are allocated for transmitting a second RS associated with the second control channel; and 
 communicating with a network device in response to at least one of the first control information and the second control information being detected. 
 
     
     
       2. A method performed by a network device, comprising:
 determining at least one of a first configuration for transmitting a first control information and second configuration for transmitting a second control information; and 
 transmitting, to a terminal device, at least one of the first control information in a first control resource set (CORESET) based on the first configuration and the second control information in a second CORESET based on the second configuration, wherein a first set of resource elements (REs) in the first CORESET are allocated for transmitting the first control information via a first control channel and a second set of REs in the first CORESET are allocated for transmitting a first reference signal (RS) associated with the first control channel, and a first set of REs in the second CORESET are allocated for transmitting the second control information via a second control channel and a second set of REs in the second CORESET are allocated for transmitting a second RS associated with the second control channel. 
 
     
     
       3. A terminal device, comprising:
 a processor configured to:
 perform a detection for a first control information in a first control resource set (CORESET) and a second control information in a second CORESET, wherein a first set of resource elements (REs) in the first CORESET are allocated for transmitting the first control information via a first control channel and a second set of REs in the first CORESET are allocated for transmitting a first reference signal (RS) associated with the first control channel, and a first set of REs in the second CORESET are allocated for transmitting the second control information via a second control channel and a second set of REs in the second CORESET are allocated for transmitting a second RS associated with the second control channel; and 
 perform communication with a network device in response to at least one of the first control information and the second control information being detected.
